I found a writeup of how to get a version of Adobe Reader 9 without the (in my case) unwanted add-ons Adobe Air and Adobe.com, from <A target="_blank" HREF=ftp://ftp.adobe.com//pub/adobe/reader/win/9.x/9.0/enu/AdbeRdr90_en_US_Std.exe>ftp://ftp.adobe.com//pub/adobe/reader/win...0_en_US_Std.exe</A>

For a silent install you can script it as
AdbeRdr90_en_US_Std.exe /sAll /rs /l /ms i/qb- /norestart
perhaps using PsExec to run it on each required PC.

There are some writeups and comments at http://www.appdeploy.com/packages/detail.asp?id=1328.

(Makes you wonder why people don't just use Foxit Reader!)
